I use xray spindles. They are stonger and they are .75mm shorter so no grinding. Use the forward most hole to duplicate the steering geometry.
Thanks for the set up sheets.

File the bottom edge, add spacer to the top edge......

Lowering the steering knuckle changes the roll center slightly. its a small change but its enough to notice it.

Use a file or a dremel with a sanding drum to take .75mm off the bottom of the steering knuckle. Then put a shim on top of it like the picture Tommy posted shows.

As Hiro and Tommy had mentioned before, it gives the car a slightly lower front roll center. If you look at some off road cars (like the Team Associated B4) they have a similar adjustment on their car. This just balances out the roll center a little better.
For me, it just resulted in more steering overall. I would only run it with 1.5mm shims under the main suspension blocks. If you use 1.0mm under the suspension blocks, AND lower the steering knuckle, it makes the roll center way to low. The car became very inconsistent and hard to drive for me. So just run 1.5mm under the suspension blocks if you want to try the lowered steering knuckle.

i guess you could do this (much more painfully) with aluminum knuckles as well?

Just about everyone starts with 1.5mm under all the suspension blocks (FF, FR, RF, RR). It's just a good starting place that works well in almost every condition. Sometimes is more grip is needed, we drop it down to 1.0mm. I can't say that I've ever tried 0 shims under the suspension blocks though.

Me and my team mate has run the blocks flat on the chassis sometimes if the grip is extremely low, that's the case when we run some of the regional series on non-permanent tracks.
